35 ft. Antenna Extension Ultra Flex Cable RP-SMA Male to N-Male MPD-400UF Super Flex White

Usually ready in 1 hour

Ultra flexible low-loss RP-SMA male to N-Male extension cable- this is MPD-400UF shielded. The cable is 35 feet long and can be used to put an extension between an RP-SMA antenna connector on a Helium miner and an outdoor antenna that has an N-Female connector. It can be used with SenseCAP, Rak, Finestra, FreedomFi, Bobcat, and other miners with an RP-SMA connector to connect to our:

6 dBi Low Profile N-Female Omni Outdoor 915 MHz
8 dBi Omni Outdoor 915 MHz

This cable will make installation around tight corners much easier and allows for repeated bending of the cable without degrading signal strength over time. Super Flex cable has a better bend radius without any additional gain loss vs a standard 400 grade cable,  

We recommend this extension cable compared to some others online because this is a special ultra flexible 400 grade low-loss cable. The antenna to which you will connect this to has a gain. Let's say you will be connecting this to a 6 dBi gain antenna. As the cable in between the antenna and device gets longer, you will experience gain loss. With lesser grade shielded extension cables, the huge drop in gain will mean much worse performance. Our special low loss cable limits the cable loss factor and preserves the high gain of your antenna.

Made in USA. This cable is American made and manufactured for superior performance and quality control.

We do recommend RokTape to seal all outdoor connection points. 

Compare gain loss:
This cable: -1.3 dB (Helium mining/LoRa device)
Cheaper RG-58 shielded cable same length: -5.4 dB

That means standard RG-58 cables have about 4x times as much gain loss as this cable! *loss shown for 915 MHz Helium frequency- loss will be different for other frequencies but 400 grade will always be a lot less than RG58

If you invested a lot in your antenna, it is worth the extra amount to get a 400 grade low loss cable to maximize your antenna performance. This goes double for Helium mining- a higher loss cable means you may be getting less reach with your miner, and therefore mining much less.

Why does this cable cost more than other options I see online of the same length?
Cables with a lower grade shielding will cost less because they consume less raw materials and are cheaper to make. This cable is also three times heavier than a CFD-200 grade cable for example, so the shipping cost is higher too- both on import, and for shipment to the end user.

Customer Reviews

Based on 2 reviews

Ive used 2 of them so far and both are a great product. Just installed my sec one and the 915 MHz 12 dBi antenna waiting to hook up my sec bobcat 300

Protective witness
Have not seen it.

I ordered it for my dad who has a couple boxes in Naples Florida he’s one of the most south boxes Omni Is not needed so I’ll probably look into directional and use the 8dbi Omni in another location. Rewards were terrible and still are but slightly less.. However I do at the fine time to get it off relay probably add VPN with router and possible an amplifier and a couple 90 degree directional sectors to aim n and straight east and a 60 minute drive is Miami.

Do you have any components that might help?
